According to a 2010 Kaiser Family Foundation report, during 2009 spent almost every waking hour outside of school using electronic devices such as iPhones, computers, or televisions. Those aged 8 to 18 spent an average seven and a half hours a day in 2009 versus six and a half hours in 2004. Calculate the annual average rate of change of electronics use for kids from 2004 to 2009.
Enter exact answer.
The annual average rate of change of electronic use for kids from 2004 to 2009 is _________ hours per day per year.
(7.5-6.5)/(2009-2004)
no it isnt, i plugged that in & its wrong:(
To calculate the annual average rate of change of electronics use for kids from 2004 to 2009, we need to find the difference in the average daily hours of electronic use and divide it by the number of years.
First, we find the difference in average daily hours of electronic use:
Average daily hours in 2009 - Average daily hours in 2004 = 7.5 hours/day - 6.5 hours/day = 1 hour/day
Next, we calculate the number of years:
2009 - 2004 = 5 years
Finally, we divide the difference in hours by the number of years:
1 hour/day / 5 years = 0.2 hours/day/year
Therefore, the annual average rate of change of electronics use for kids from 2004 to 2009 is 0.2 hours per day per year.
